| Abstract: | Piroplasmosis is a zoonotic protozoan disease transmitted by ticks. The full geographical range of canine piroplasms has been found in dogs in the Middle East, parts of Africa, North America, and Europe. Following our studies on molecular detection of piroplasmosis in the south of Iran, we found Theileria annulata in two herd dogs, as well as information on their 18S rRNA gene sequences. Piroplasmosis agents were detected by PCR of 280 blood samples collected from dogs in seven regions of the Shiraz suburbia in southern Iran, between November 2009 and June 2011. Two positive samples from Shiraz were infected with T. annulata, and one sample was infected with Babesia canis. PCR positive samples were further analyzed by sequence analysis. The results of this study reconfirmed that T. annulata are not always as host specific as accepted. This is the first report of T. annulata in herd dogs in southern Iran and the second report of T. annulata in dogs worldwide. |
